lll;

bus bars 20, switches 21:tuses 22, and circuit terminals 23, is rectangular in shape and rests, with its corners, upon the corner segments 18 of the bracket members 13,'the corners ot the panel board 19 passing between the cheeks 15, as indicated by the dotted line in Fig. 4f.

Passing through the tie 1G of each bracket member 13 is a screw or bolt 25 having for a head the member 26 having faces disposed at right angles to each other and adapted to engage the inside faces o the linings 27 which may be rormed of slate or other suitable insulating material, disposed at right angles to the panel board 19. A wing nut :'23 on the outside et the tie 1b serves to draw the member 2b .lirmly against the insides ot the linings 2T and hold them firmly against the cheeks l5 and thus tirmly in position, the linings 2T and the panel board 19 forming a shallow open box of insulating material.

Passing under the wing nut 28, and clamped between it and the tie 16, is a further clamp 29, as shown in Fig. 5, slotted at` 30' to be adjustable with respect to the screw The clamp 29 terminates in a head Ill at right angles to the portion 29 and ei'igagrs the top corners of the linings 2T. The linings do not come together attheir corners but leave a gap through which the screw passes. Between the linings 27 and the inside of the casing or holder l is left a trough in which are laid the electrical conductors leading to the bus bars 20 and the circuit terminals 23, such conductors passing ont to the dillerent circuits in the building through any suitable Opening.

Daring the construction of a. building, the holder or casing l, with the attached angle members 'l is built in or secured in posit-ion in a partition wall, the top or front edge of the holder being placed to come approximately flush with the rall. Upon the completion or the building, the wooden trim or molding is placedas an ornamental inish to cover the holder or casing, an opening for the door 233 being provided, such door having dass panel 3ft, it' desired, the door opening ng substantially the same size and shape as the panel board. Later, or before the trim 32 is put in place, the brackets 13 are placed and then the panel board l) and the linings 2T, the bracket-s 13 being slid or adjnsted with respect to the angle members 4e and then tightened when the panel board is in alinemcnt Willi the trim, irrespective of whether the holder l is askcw or in alinemcnt. nd the linings 2T are clamped by the means described, that is, both by the member 26 and the-clamp 29.

From the foregoimr description, it is apparent that the panclkboard and linings need not he drilled for the reception oi" screws. or other fastening means, but that they may be neofita adjustably secured in position by clamping screws or bolts carried by members which are suitably adjustable to compensate for any lack of alinement between the casing or holder and the outside tinish upon the wall.

The parts being, preferably, of sheet metal, such as sheet iron, and ot castings, cast iron or malleable castings, and there being no drilling or accurate fitting ot the parts required, atl'ords a cheap and yet highly elicient structure and mounting for panel boards.

Wlhat we claim is:

l. The combination with a plate, of angle members secured thereto, bracket members, means fo adjustably clamping said bracket members to said angle members, a panel board, said bracket members having sockets to receive said panel boards, linings, and means for clamping said linings to said bracket members.

2. In a panel board mounting, the combination with a plate, of slotted angle members secured thereto,=slotted brackets, means for adj ustably securing said brackets to said angle members, a panel board., saidI bracket members having openings to receive said,

panel board, linings, and means for clamping said linings to said bracket members.

2S. ln a panel board support, an angle member having legs disposed substantially at right angles to each other and in the same plane, said legs having slots to receive ad-l justable securing means, a panel board, and a support therefor attached to said angle member.

4. In a panel board support, a bracket member` comprising slotted legs disposed at right angles to cach other, cheek members on said bracket member, there being a gap between said cheek members to receive a panel board, and a tie between said cheek members.

5. In a panel board mounting, the combination with an adjustable bracket member, of a supporting member means for securing bracket member to said supporting member, and a lining clamp on said bracket member, said bracket member having an' opening to receive and support a panel board.

G. in a panel board mounting, the combination with an angle member, of a bracket member, said angle and bracket members cach having slotted legs disposed at an angle to each other, m xaus for adj ustably securing said bracket member to said angle member, and a panel board supported by said bracket member.

T. In a panel board mounting, a bracket member having an opening to receive and supporta panel board, and a clamp on said bracket member for clamping a lining thereto.

8. In a panel board mounting, a bracket member comprising cheek members, a tie and a corner plate joining said cheek members, said bracket member having an opening formed between said tie and corner plate to receive a panel board.

9. In a panel board mounting, a bracket member having cheek members disposed in planes at right angles to each other, a clamp carried by said bracket member between said cheek members for clamping linings against said cheek. members, a member of said clamp extending between said linings.

10. The combination with a sheet metal casing, of angle members secured thereto, bracket members adjustaby secured to said angle members, said bracket members having openings to receive and support a panel board, and lining clamps on said bracket members 11. In a `panel board mounting, the combination with angle members, o bracket members adjustably secured thereto, Said bracket members having openings to receive a panel board, and lining'elamps on said bracket members.

l2. In a panel board mounting, a bracketl member, a lining, a clamp on said bracket member for engaging a side of said lining,

and a second clamp on said bracket member engaging an edge of said lining.

lin testimony whereof We have hereunto allixed our signatures this 16th day o'July,

1908, in the presence ofthe two subscribing,
